' Lettors Patent No. 87,252, dated Februaxry 23, 1869.

T0 all wwm it may concern:

Be it known that I, ANTHONY FUHRMN, of Ll0yds: ville, in the county ofFerry, and State of Pnnsylvania, have invented a new and useful Gouplingfor Thills, Traces, Whiffle -Trees, &c.; and I dohereby declare that thefollowing is a full, clear, and exact descrip- (ion thereot, referencebeing had to the acoompanying dra.wings, and to the letters of referencemarked thereon.

'Ihe nature of my invention consists in 50 constructing a coupling'forthills, traces, whifde-trees, &c., that it may be easiy and secnrelyadjusted in the dark'as well as in the light,-and, when used as athillconpling, will furnish a secure and simple means for holding thethills in an npright position, when desired.

To enable others skilled in the art to which my invention appertains, tomake and use the same, I will proceed to describe its construction andoperaton.

In the dmwings A represents the thilliron, provided:with a crossiiead,C.

B represents the axle-iron, which may be fastened to the axle' by clipsin the nsual manner.

The axleiron B has two eyes, d 6, which receive and hold the cross-head'O. V

The eye d has a slot, J, and the eye 0 has a notch, g, formed as shown.

lhe portion of the thilliron nearest the cross-head 0 is madewedgeshaped, and thinnr than the other portion, as shown at X.

In attaching the thills, the end 0 of the cross-head -0 is innerted inthe eye d, the thills raised to an upright position, and moved iaterallyuntil the thin portion X has passed the 3101; f, and then lowered 130the position shown in Figure 1. Ibis motion is reversed in detaching thethills.

When itis desired'to have the thills ofi' the ground, and out of theway, without detaching them, they are raised to-au upright position, andmoved laterally,,nntil the thin portion X engages with the notch g,which holds the thills in the position shown in Figure '2.

This conpling may be used for a trace-coupling, by bending the axle-ironB, and attaching it to the end of the whiffle-te, and attaching' thetlfiliron A to the end of the trace.

It may also be used for a whiflie-tree conpling, by attaching thethilliron A to the whiflie-tree, and the axleiron B to the whifile-treebar, the form of the parts A and B being modified to suit suchattaohment.

Having thus descrtbed my invention,

What I daim, and desire to secnre -by Letters Patont, is-

A thill-couplng, constructed with a notch, g, or its equivalent, in theeye 6, and a projection on the crosshead 0, corresponding with the 5101:f in the eye d, substantially as herein shown and described, and for thepurpose specified.
